Microplastics do not increase bioaccumulation of petroleum hydrocarbons in Arctic zooplankton but trigger feeding suppression under co-exposure conditions
Arctic sea ice has alarmingly high concentrations of microplastics (MPs). Additionally, sea ice reduction in theArctic is opening new opportunities for the oil and maritime industries, which could increase oil pollution inthe region. Yet knowledge of the effects of co-exposure to MPs and crude oil o...
